FINDER LIGHT.

Application filed March 4, 19,22. Serial No. 541,228.

To all whom t may concern.'

Be it known that we, CLEMENT J. W'ERNER and JOSEPH H. SMART, citizensofl the United States, and residents of Dorchester, in the county ofSuffolk and State of Massachusetts, have invented an `lnriprovement in Findei Lights, of which the following description7 in connect-ion wit-hthe accompanying drawings, is a specification, like letters on' thedrawings representing like parts.

Our present invention is directed to a novel light holder, finder,switch and detachable and' adjustable mirror.

Our invention is particularly directed as an article for use inconnection with automobiles or other electrically operated machinery ordevices, one kof the important features being the non-conductingconstruction of the holder'.

A further important feature consists in theY arrangement of the holderor handle, the light, and switch construction, this being of specialimportance in articles of this kind for quick operation-both on andolfby means of the operators hand which holds the handle, therebyleaving the other hand free.

While our non-conducting finder light is suitable for use and iscomplete in itself, we have also provided a novel and quickly attachableand detachable as well as adjustable detecting apparatus for use inconnection therewith. This feature is of particular importance in workabout machines or the like where inaccessibility renders such workdiiiicult. l p

In carrying out our invention we provide V a suitable length of a handleor holder, preferably non-conducting and yet ofsuiiicient strength tocarry the light, conceal and protect the wires, be 'provided with ournovel form of switch, and facilitate the positioning of the light at anypoint desired. This handle or holder may be of fiber, vulcanized rubber,or other non-conducting material to eliminate all danger of the operatorreceiving shocks therefrom when working about electrical machinery, aswell as to prevent all danger of lire by short circuiting or arcing. Tothis holder the light and refiector attaching and adjusting means areassembled, as will be explained.

Referring to the drawings, illustrating a preferred embodiment of ourinvention,

Fig. l is a side view of our improved device with. the reector abtahed;

Fig. 2- is a view at right-angles to that Fig. 4 is a cross-sectionalview on the line Ll 4 of Fig. 3; illustrating the construct-ion of theswitch; and l Fig. 5 is a further detail.

Our improved form of 'finder and holder can be of any suitable size, butas here illusi trated is adapted for ordinary use and is of a convenientsize, the entire weight being trivial so as not to tire the operato-r, a

further feature obtained by the non-conducting or fibrous handle. l

Our apparatus consists .in a tubular member or handle 1, formed toreceive and carry the current conducting wires 2, which may be of anysuitable or desired length. One end ofthe tube may be enlarged slightlyas shown at 3 to carrythe socket (not shown) for the usual electriclight bulbi 5.` At the opposite end is the'switch which lwe havespecially devised for use in connection with this apparatus. 'Thisswitch is formed to -t within the shell of the tube or, handle l andconsists in anon-conducting tubular portion' 6 carrying imbedded thereinmetallic conductors 7 and 8, spaced slightly from each other. Theseconductors can be readily fitted into the tubular portion 6- thelat-ter" being preferiably of liber-by sawing a groove into the sainekand `then fitting r`the members 7 Aand 8 therein, as

Clearly shown in Fgs- 4t and 5. The outer# 4' most portionrof the member6 Vis reduced in diameter to receive thereabout a brass Vor othermetallic conducting member 10, to

which latter Vis threaded a handle 12,v adapt- Y l ed to project outsideofthe tube l and through a slot or recess' 15 formed in the end of thetube, as best illustrated' inFigs. 7

terminals 7 and 8 will be connected or dis connected as desired. Aferrule or finish.

16 is added for convenience, appearance and to aid in holding thehandle.

Our apparatus as thus far described is I complete and useful for afinder light for any apparatus and being non-conducting is of especial,usefulness and importance in.

working about an automobile or other machinery where electrica-l devicesare employed. No danger to the operator is possible from the lightcoming in contact with charged wires or portions of the machinery, owingto t-he non-conducting handle.

In order to still further equip this apparatus for usefulness, we applya reflecting mirror thereto. To this end a tubular ferrule 2O having aninterior diameter suitable to lit over the enlarged portion 3 adjacentthe light of the finder, is formed, which ferrule 2O is preferablymetallic and may have strengthening ribs or grooves 21 and 22 and whichalso is partially split lengthwise and transversely, as shown at 24; and25, to afford a springlike grip upon the portion S of the handle. A pin27 fitted in the handle is adapted to cooperate with a bayonet jointgroove 28 Vin the bottom of the vferrule, to facilitate, fitting andVlocking the ferrule 20 onto the handle.

Attached to the ferrule 20 is a boss 30, which may and preferably doesconsist in a pair of flanges 31 and 32, these terminating in a roundbearing to receive the shank of a bolt or stem 33. Preferably this stemis threaded and lits into a correspondingly threaded reinforcement orlug 34. The head of the bolt, 36, affords a bearing on the opposite sideof the upstanding flange, and a handle 38 facilitates the partialrotation of the same, to afford a clamping action or release thereof onthe detachable mirror. This mirror consists in any suitable reflectingsurface and is designated generally at 40, including a back or holder towhich is secured an arm Lll. This arm lll extends in the form of agooseneck with an open slotted part adapted to fit over the stem 33 ofthe bolt and between the 'flanges 32 and 3l. This construction isclearly shown in dotted lilies in Fig. 1. `With the mirror thus appliedthe handle 38 is partially rotated to bind and clamp the slottedgooseneck end of the bracket 41 between the flanges 32 and 3l, thusholding the mirror firmly in position, while permitting quick adjustmentfor the angle desired.

It will be noted that the entire apparatus is compact, neat, can bereadily assembled for use and with the mirror detachable and the entiremirror holding' ferrule removed,

facilitating packing, shipping and carrying. automatic limit or stop tocontrol the actions ,of the switch, and this switch is so positioned,designed and constructed that the operator, with one 'hand holding theapparatus, can turn the switch on or olf with a slight movement of thefinger, and independently, thus 'freeing his other hand at all times.For work about an automobile, effecting adjustments, or any other workrequiring light, peculiarly positioned and quickly placed, our apparatuswill be found of great usefulness.

llfith the ferruleQO applied, and when the mirror is used, the ferrulepreferably slightly overlaps the bulb of the light 5, thereby protectingthe same and also concentrates the rays of the light upon the mirror. Toaid in this action, the interior of the ferrule 2O may be silvered orotherwise coated to reflect the rays of light diused thereagainst, thusconcentrating the rays of light upon the mirror and thereby greatlyincreasing the efiiciency of a small lamp.

Our invention is 'further described and defined in the forni of claim asfollows:

A finder light of the kinddescribed, comprising an elongated cylindricalhandle member of non-conducting material7 an electric light bulbremovably secured thereto at one end, conductors included in circuitwith said bulb and extending through the interior of said handle, aswitch included in circuit with said conductor and loca-ted within thehandle at the end remote from the bulb, an operating handle for saidswitch extending laterally outward from the handle and rotatable aboutthe longitudinal axis of the handle, said handle being provided with acircumferential slot through which the operating handle of the switchextends and which limits the rotative movement of the operating handle,a cylindrical casing slidably mounted over the handle adjacent the bulband provided with laterally extending lugs, and a protecting mirroradjustably mounted in said lugs.

In testimony whereof, we have signed our names to this specification.
